Device that crowd-sources water quality introduced at TEDGlobal conference

Researchers at the TEDGlobal conference in Edinburgh, Scotland, this week described a device that crowd-sources water quality to "chec[k] supplies in real-time, alerting users to possible infections," and "upload[s] the data, allowing scientists to monitor the location and movement of outbreaks," BBC News reports. The researchers said the device, called the Water Canary, "could prove invaluable for governments around the world keen to contain disease and environmental disasters," according to the news service (Wakefield, 7/13).
